javascript - How serialize objects with angularjs -

how can serialize object without using $.param jquery?

i want object below:

var user = {username: 'ronald.araujo', password: '123456',}; 

to have following output:

username=ronald.araujo&password=123456 

any suggestions? remembering using angularjs or pure javascript.

edit:

i using verb "save" ($resource) angularjs. how set header "application / x-www-form-urlencoded" , serialize?

pure javascript can fine:

function serializeobj(obj) {      var result = [];        (var property in obj)          result.push(encodeuricomponent(property) + "=" + encodeuricomponent(obj[property]));        return result.join("&");  }    var user = {      username: 'ronald.araujo',      password: '123456'  };    var serialized = serializeobj(user);  console.log(serialized); //username=ronald.araujo&password=123456
